I mean if you're not gonna track the car, is it going to make that much of a difference to pony up an extra $400 - $500?

Pretty sure the AA would be a considerable improvement over stock for daily driving and the occasional track day, especially for those not wanting to go crazy with huge turbos / meth / etc... later on. I don't need an FMIC that can take 600+ hp, I'm never going to build the car that much anyways.

That is why i have to know how intense the install is! If i have to pay a lot to just install it, then i would take the bigger one...
